Burn-resistant and high tensile strength metal alloys

Abstract

Burn-resistant metal alloys that also have a high tensile strength are described. The alloys generally include about 55 to about 75 weight percent nickel, about 12 to about 17 weight percent cobalt, about 4 to about 16 weight percent chromium, about 1 to about 4 weight percent aluminum, and about 1 to about 4 weight percent titanium.

1 . A burn resistant, oxidation resistant and high tensile strength alloy, consisting of:
 70 to about 75 weight percent nickel;   about 10 to about 17 weight percent cobalt;   about 6 to about 15 weight percent chromium;   about 1 to about 4 weight percent aluminum;   about 1 to about 4 weight percent titanium;   at least one of carbon, boron, or zirconium;   wherein the alloy has a tensile strength of at least about 145,000 pounds per square inch;   wherein the alloy is oxidation resistant; and   wherein the alloy has an extinguishing threshold pressure of at least about 4,000 pounds per square inch.   
     
     
         2 . The alloy of  claim 1 , wherein the chromium content is about 7 to about 9 weight percent.
